To (/ZZ whom it may concern: t

Be it known that I GLOIOEB. BAKER, a states, residing at St. Louis,state of Missouri',,have invented certain new andusefulImprovements inHandrail-Columns, of which the "following is a 7 being had to theaccompanying drawings,

forming a part hereof- Y The present invention is directed toimprovements in hand rail columns or brackets, particularly as appliedto locomotlves. As well understood in the art, a'locomotive boiler isusually covered with a lagg'ing of asbestos or mineral wool which isprotected by an outer metal sheet or jacket usually:

made up of sections wrapped around the boiler. The studs to'which'thehand rail columns are secured pass through the lagging andjacket, the outer ends of the studs being screw threaded to receive thethreaded sockets of the columns, the :outer ends of thecolumns'terminating in loops or, eyes through which the handrail ispassed. When it becomes necessary for any reason to remove one of thejacket sections, the hand rail must first be withdrawn from the eyes ofthe supporting columns to permit the unscrewinj of the columns from thestuds, after which the jacket is'pulled out from the studs and removed.Such removal of the jacket. is necessitated for example in cases where,a leak in the boiler is to be stopped orother repairs made to the boilershell. The object of my invention is to provide a hand rail column orbracket which does not require the removal of the hand rail whenoccasion arises to take down a section ofthe outer jacket. This ofcourse is adecided advantage in thatitnot only saves time and laborbutdispenses with the necessity of making the handrail in sections whichwiththe ordinaryicolumn must be done to facilitate withdrawal of therail from the supportingloops or eyes of the columns. Under my inventionthe column is made in two sections which may be separated fromoneanotherat any time, one of the sections (the one carrying the'loop) beingslipped along the rail out of the way while the other section or thatcoupled .to the securing stud can be readily unscrewed from the studwithout disturbing the rail.

The advantages of the invention will be more fully apparent from thefollowing dethe same are assembled. threadedexten'sion 6 is ofiset fromthe loop v a connection with the ac companyingldrawings in which' Fgure 1. represents aside elevation of a locomotive showing my inventionapplied thereto; Fig. 2 is anenlarged' cross-section through the boilershell, the lagging, and outer jacket thereof, showing my improved taileddescription in columninelevation, applied thereto; Fig.

3 is a detached elevational view of the improved colu nn; Fig. 4 is alon itudinal middle section therethrough; and 1s a perspective of acolumn parted so as to permit the shifting of the outer section alongthe hand rail.

, Referring to the drawings, 1 represents the shell of the boiler, 2,the lagging, and 3 the outer jacket, the studs 4 leading from the shellor boiler wall through the lagging and jacket and terminating at their'outer ends in athreaded portion to which the columns or brackets aresecured as well understood in the art. I In the present embodiment ofmy'invention the hand rail column is composed of two sections ormembers,the inner or bot tom section comprising an intermediate cylindricalportion .5 terminating at one end in an expanded base 5, and at theopposite end in aslightly enlarged threadedportion 5f, the bottom of thememberbeing pro- .vided with the usual threaded socket a foreye 6 forthereception of the hand rail 7 as usual in the art, and an innerreduced threaded portion or extension 6" of the same cross-section asthe threaded portion 5 of the first section, the ends of theportionslbeing brought into abutting relation when The reduced 6 by aninclined outwardly flaring shoulder 8, said shoulder receiving thecorrespondingly beveled end of a coupling sleeve 8 screwed overthe'threaded "portions 5, 6, the length of the sleeve corresponding tothe combined lengths of the threaded portions over which the same ispassed. The length of the intermediate portion 5 of the innercolumnsection is sufficient to allow the sleeve 8 to be wholly unscrewed. fromthe threaded portion 6 of the outersection so that when occasionrequires, said outer secti on may be readily detached from the bottomSpecification of Letters Patent. Patented July 6 192() section (Fig. 5;also dotted lines Fig. 4). In practice, when occasion arises to remove asection of the jacket 8, the operator simply unscrews the couplingsleeve 8 sufliciently to separate the two-sections of the column,

the outer section being then moved along the rail 7 out of the way ofthe bottom section to be removed (Fig. 5). With the outer column sectionout of the way, the bottom section of the column is then unscrewed fromthe stud f, permitting the jacket'to be passed off the stud and therebyremoved from the boiler without disturbing the hand rail. In thesame'manner the lagging may be passed sleeveS screwed home againstthershoulder s, and this without the necessity of disturbing the handrail. The column is therefore a time saver and reduces the cost ofrepairs. It is of course apparent that I may change the construction inminor details'without departing from the nature or spirit of the in- Lvention. The advantage of the present construction lies in the fact thatwhen the cou pli'ng'sleeve which spans. the joint formed by the abuttingterminals between the column sections is moved past the point or unscrewed sufficiently to release the outer section, the latter can bemoved to one side or in a direction at right angles to the axis, of thecolumn. 'The outer section beingthus moved to one side, allows thebottom section to be removed independently from the securing stud4without disturbing the hand rail. i

Having described my invention what I claim is,

j 1. A hand rail column comprising an outer section to which the rail isapplied, and an inner section to be attached toa fixed support, andseparable from the first section, and means disposed about theperipheries of the sections for coupling the sections together.

2. A hand rail column comprising an outer section to which the rail isapplied, an inner section, means on the bottom of said inner section forsecuring the same to a fixed support, and means engaging the peripheralwalls of the sections for coupling the sections together. I

3. A hand rail column comprising an outer section to which the rail isapplied, an inner section, means on said inner section for securing thesame to a fixed support, and a movable member encompassing adjacentportions of the sections for coupling the sections. 1

4. A hand rail column comprising an outer section provided with a handrail-receiving loop and a reduced threaded exten- V sion leading andoffset therefrom, a bottom section terminating at one end in a threadedportion'of the same cross-sectional. diameter withthe reduced threadedextension of the outer section and adapted to be placed in abuttingrelation therewith, the bottom section having a slightly reduced portionleading from the inner end of the threaded portion thereof, a couplingsleeve passed over sections in abutting relation disposed about a commonaxis, a coupling sleeve spanning the joint between the sections andadapted to be moved past the joint aforesaidkto allow one of thesections to be moved in a direc-' tion at right angles to theaxisaforesaid.

7. A hand rail column comprising a bottom section having at one end anexpand,

ed base, a central reduced portion, and a slightly enlarged threadedportionat the op posit'e end, and anouter section composed of ahandrail-receiving loop and of a reduced threaded extension leading andoffset from 1 the looped portion by an inclined outwardly flaringshoulder, the threaded portions of the sections being of the samecross-sectional diameter and forming a butt joint with one another, ascrew sleeve passed over the threaded portions and spanning the jointaforesaid for coupling the sections together, one end of the sleevebeing beveled to engage the inclined shoulder aforesaid, the lengthoftheintermediate reduced portion of the bottom section being such as toallow the.

sleeve to be fully unscrewed from the threaded extension of the outersection, thereby permitting said section to bemoved to one sidealong therail to permit removal of the bottom section. I r

In testimony whereof I afiix my signature, in presence of twowitnesses.-
